Best Cooling Mattress 2026: 7 Picks for Hot Sleepers

The best cooling mattress for hot sleepers is the Saatva Latex Hybrid. It posts the highest cooling score in our entire database (8.6 at RTINGS), pairs it with the best durability of any coil bed we track (8.3), and holds three separate RTINGS awards for 2026. It is expensive, at roughly $2,346 for a queen, and it is firm. But if heat is the thing waking you up at 3 a.m., it is the bed with the strongest evidence behind it.

If that price is a non-starter, the DreamCloud Classic Hybrid at about $699 is the best cheap cooling mattress. RTINGS measured 7.9 for cooling — the same as beds costing twice as much — and Sleepopolis named it a top choice for hot sleepers. And if you want the most-decorated cooling bed of the last year, the Bear Elite Hybrid won Tom’s Guide’s Best Cooling Mattress at its 2025 Sleep Awards and comes in three firmnesses.

The pattern behind those picks is simple and, frankly, more useful than any brand’s “cooling technology” page: latex and coils sleep cooler than dense memory foam, and how deeply you sink matters as much as any gel or special cover. Every one of our top four picks has either a latex comfort layer, a coil support core, or both. The three beds at the bottom of our cooling ranking are all-foam.

Our seven winners, chosen on measured cooling first, then support, durability and price. Click through for the full evidence on each.

You produce heat all night, and your body actually needs to shed some of it to fall and stay asleep. A mattress can help or hinder that in three ways: how much of your body it wraps around, whether air can move through it, and whether the materials themselves hold on to warmth. Most “sleeps hot” complaints in owner reviews come down to some combination of the three.

Surface contact. Traditional memory foam is designed to soften with body heat and mould around you. That slow, hugging sink is exactly what pressure-sensitive side sleepers love, but it also means more of your skin is pressed into insulating material, with less air around it. A firmer foam bed you lie on top of can actually sleep cooler than a plush one. That is one reason the firm Zinus Green Tea, a cheap all-foam bed, still scored a respectable 7.5 for cooling at RTINGS, while softer, deeper foam beds often score lower.

Airflow. A layer of pocketed coils is mostly empty space. Every time you shift, the coils compress and rebound, pumping air through the core of the mattress and out the sides. A solid block of foam has no equivalent. That’s why, almost without exception, hybrids outscore their all-foam siblings from the same brand. Nectar is the cleanest example: the all-foam Nectar Classic scores 7.2 for cooling, while the Nectar Classic Hybrid — similar comfort foams, with coils swapped in for the foam base — scores 7.9.

Material. Natural latex is made from rubber-tree sap whipped into foam and usually cored with pinholes. It is springy rather than slow, so you sink in less, and its open structure lets heat dissipate more readily than dense memory foam. Combine latex with coils and you get the two coolest beds in our database: the Saatva Latex Hybrid (8.6) and the all-latex Saatva Zenhaven (8.3). The Bear Natural, another latex hybrid, also lands near the top at 7.8 — despite its other weaknesses.

Put those three mechanisms together and you get a clear hierarchy. Averaged across every model we track, latex hybrids lead, coil hybrids follow, and all-foam beds trail. Innersprings sit slightly lower than you might expect only because our two examples are a heavy-duty bed tuned for 300-plus-pound sleepers and a model whose pillow top adds insulation — Sleep Foundation still gave the Saatva Classic a perfect score for temperature.

One more thing that rarely appears in marketing: firmness and body weight change how hot a bed feels. A heavier person sinks further into the same mattress than a lighter person, compressing more foam around them. If you weigh more than about 230 lb and sleep hot, lean toward firmer, coil-based or latex beds — and read our guide to the best mattress for heavy people, where cooling and support overlap almost completely.

Here is every model in our database — 24 beds across Saatva, DreamCloud, Nectar, Puffy, Bear and the Amazon budget brands — sorted by cooling. Where RTINGS has tested a mattress, the number is RTINGS’ measured cooling score. RTINGS runs a repeatable heat test rather than asking testers how they felt, which is why we lean on it first. Where it hasn’t, we use Sleep Foundation or Sleepopolis temperature scores, adjusted down about a point to match RTINGS’ stricter scale (see how we rate).

Read the chart top-down and the colours tell the story. The dark-blue latex bars cluster at the top. The light hybrid bars fill the middle, mostly between 7.0 and 8.0. The pink all-foam bars are scattered, but the bottom three spots — the Siena (5.8), the Puffy Cloud (6.3) and the Bear Original (5.5) — are all memory foam. The one surprise is the Nectar Premier, an all-foam bed RTINGS measured at a strong 8.0; we discuss why other testers disagree below.

Our cut-off for “a cooling mattress” is simple: 7.8 or above. Anything in that band will feel noticeably cooler than a typical foam bed for most people. Between 7.0 and 7.7 is “neutral” — fine unless you are a genuinely hot sleeper. Below 7.0, assume you will notice heat on warm nights, and budget for cooling bedding.

The Saatva Classic row is the encouraging kind of disagreement: the lab gives it a good-not-great 7.4, while Sleep Foundation gave it a perfect 10. The DreamCloud Luxe row is the worrying kind. Its lab-based number looks fine, but Mattress Clarity scored cooling just 2.5 out of 5 and two of three expert testers called it warm. A 14-inch pillow top full of soft foam is exactly the sort of design our physics section predicts will trap heat, so we have left it off our list.

Walk through any mattress website and you’ll see the same promises: gel-infused foam, copper, graphite, “cooling covers”, and phase-change materials. Some of these do something. Very few do as much as the marketing implies, and none of them can turn a deep, dense memory-foam bed into a latex hybrid.

Phase-change materials are the most scientifically interesting. A phase-change material, in the textbook definition, is a substance that “releases/absorbs sufficient energy at phase transition to provide useful heat or cooling”. In bedding, the material is micro-encapsulated into the fabric or a thin layer just under it. When your skin warms it past its transition temperature, it absorbs heat as it melts — which is why these covers feel cool when you first lie down. The catch is capacity: once that thin layer has finished absorbing heat, it stops cooling until it has had a chance to release the heat again. Think of it as a buffer that helps you fall asleep, not an air conditioner that runs all night.

Gel, copper and graphite infusions are added to foam to conduct heat away from your body slightly faster. They help at the margins. But the Bear Original is a useful reality check: it uses gel memory foam, and it still has the lowest cooling score in our database (5.5), with Sleep Foundation rating its temperature control just 6 out of 10. The infusion cannot overcome a solid block of foam with no airflow underneath.

Optional cooling upgrades are where brands quietly admit the base model is warm. Bear sells a Celliant cover on its cheaper models and an optional CoolForce layer on the Elite Hybrid — both cost extra, and the Elite’s 7.9 cooling score at RTINGS is for the bed as tested. Our advice: buy the right construction first, then decide whether an upgrade is worth it, rather than paying to fix the wrong bed.

Saatva Zenhaven — best all-latex. The Zenhaven is all Talalay latex, flippable, with a Luxury Plush side and a Gentle Firm side. With no coils, it still scores 8.3 for cooling, which shows how much the material matters. Durability is excellent (8.3; Sleep Foundation 9 out of 10), and Sleepopolis rated it 4.8 out of 5. It loses ground on motion isolation (5.0) and edges (5.5), and at about $3,145 it’s the most expensive bed on this page. Pick it if you sleep hot and can’t decide how firm you want your bed.

Saatva Classic — best innerspring. Sleep Foundation gave the Classic a perfect 10 for temperature control, and its coil-on-coil build is exactly the airy construction hot sleepers want. RTINGS measured a more modest 7.4 on Luxury Firm. Three firmnesses and two heights make it the most adjustable hot-sleeper choice, and edge support (8.2) is strong. The trade-off is motion: if your partner tosses, you’ll feel it. Our Saatva review covers the firmness choice in detail.

Nectar Classic Hybrid — best for foam lovers. If you love the slow hug of memory foam but hate waking up warm, this is the compromise. Mattress Clarity named it its top hybrid pick for cooling (4.5 out of 5) and Sleep Foundation rated temperature 8. RTINGS measured 7.9 — a clear step up from the all-foam Nectar Classic’s 7.2 — and motion isolation is an excellent 8.6. At about $849 it’s our second-cheapest cooling pick. RTINGS did flag lower-quality memory foam and longevity of 5.7. Compare it with its siblings in our Nectar review.

DreamCloud Premier Hybrid — for side sleepers. Side sleepers usually need a softer bed, which usually means more foam and more heat. The Premier is the exception the lab data supports: RTINGS measured cooling at 8.0 alongside a strong 8.1 for light and average side sleepers. But Mattress Clarity and Tom’s Guide both scored its temperature regulation only 3.5 out of 5, so treat this as a conditional pick. If you’re a side sleeper who runs very hot, the Saatva Classic in Plush Soft is the safer coil-based alternative; our best mattress for side sleepers guide has more options.

A good guide tells you what not to buy, too. These beds are fine for plenty of people, but if you’re searching for a cooling mattress, the evidence says to look elsewhere:

• Bear Original (cooling 5.5). The lowest score in our database. Gel memory foam doesn’t compensate for an all-foam build; Sleep Foundation rated temperature 6 out of 10. Bear itself sells a Celliant cover upgrade, which tells you something.
• Siena Memory Foam (5.8). A good cheap bed for back sleepers, but Sleep Foundation noted heat retention, and it’s a 10-inch slab of foam.
• Puffy Cloud (6.3). Average cooling at best. If you want Puffy’s plush feel, the Royal Hybrid (7.7) is cooler, though pricier.
• DreamCloud Luxe Hybrid. Not low on paper, but two of three expert testers found it warm and Mattress Clarity scored cooling 2.5 out of 5. Its thick pillow top is the likely culprit.
• Nectar Premier, with a caveat. RTINGS measured an impressive 8.0, but Sleep Foundation scored temperature only 6.0. If you love foam, try it — with the 365-night trial as your safety net.

Notice that most of the avoid list are beds that do other things very well. The Nectar Premier has top-tier motion isolation (8.8) and won Tom’s Guide’s best memory foam award; the Bear Original is a solid firm bed for back sleepers on a budget. Cooling is a trade-off, not a verdict on the whole mattress. If you’re cold-natured or sleep in air conditioning, ignore this section.

The table below puts all seven picks side by side with their Research Score, firmness, cooling, motion isolation and owner ratings. Cooling and motion are shown as dots, so you can see the trade-off at a glance: the coolest beds tend to transmit more movement, because the same springy, open construction that moves air also moves your partner’s tosses and turns.

Two things stand out. First, price and cooling are only loosely related: the $699 DreamCloud Classic Hybrid ties the $1,599 Bear Elite, and the $3,145 Zenhaven sits below the $2,346 Latex Hybrid. You are paying for durability, materials and features, not just temperature. Second, firmness clusters between medium and firm. That’s not a coincidence — firmer beds let you sleep on the surface rather than in it, and our ranking reflects that physics.

If you’d rather we just pick, here’s our opinionated shortcut by sleeper type and budget.

Still not sure? Our 30-second mattress finder weights cooling more heavily when you tell it you sleep hot, then balances that against your position, weight and budget.

A cooling mattress is the biggest single change you can make, but it isn’t the only one, and some of the others are free. Before you spend $2,000, check the things touching your skin and the air around you.

Sheets and protector. A thick, plasticky waterproof protector can undo a cool mattress overnight. Look for breathable protectors, and choose cotton percale or linen sheets over heavy sateen or polyester microfibre. Pillows. Your head is a major heat outlet; a dense memory-foam pillow can feel hot even on a cool bed. Bedroom. A fan that moves air across the bed does more than most cooling covers. Toppers. A latex topper can cool down a warm foam bed slightly, but a memory-foam topper will almost always make a hot sleeper hotter.

Finally, think about the bed frame. Coil and latex mattresses breathe best on a slatted or open base. A solid platform under a foam bed blocks one of the few routes heat has to escape. (The exception: the Zenhaven needs a solid foundation for support, not slats.)
